An issue was discovered in PHPMailer before 5.2.22. PHPMailer’s msgHTML
method applies transformations to an HTML document to make it usable as an
email message body. One of the transformations is to convert relative image
URLs into attachments using a script-provided base directory. If no base
directory is provided, it resolves to /, meaning that relative image URLs
get treated as absolute local file paths and added as attachments. To form
a remote vulnerability, the msgHTML method must be called, passed an
unfiltered, user-supplied HTML document, and must not set a base directory.
